    Posted: 15 September 2008 at 8:10pm
Hi,

We are running Spamfilter ISP v4.0.1.785 and we are having a problem with the filter accepting new connections after a period of time. The port is still open however if you telnet to port 25 it just disconnects. The logs for the Spamfilter stop processing mail and just repeat the bayesian thread loading of the corpus db and cleanup. To resolve we have to restart the server as the service will not respond to a stop/start or restart.

We have gradually increased the MaxInboundConnections to 500 however the issue continues to occur (more frequently of late). Below is the log that just continually repeats until we restart the server:

Can you please zip and email us SpamFilter's entire activity log for a day this happened, so we can scan it for problems? If the file is over 5MB in size, please upload it to our FTP site. I'll be sending you a PM with the ftp login information.

Your logs contain a few instances of these errors:

09/15/08 11:05:52:078 -- Exception occurred during PerformPostStartupTasks: Could not bind socket. Address and port are already in use.
09/15/08 11:09:22:468 -- Exception occurred during PerformPostStartupTasks: Could not bind socket. Address and port are already in use.


The issue is exactly the same we described in your earlier post at http://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=6533. Multiple instances of SpamFilter (probably both the service and the standalone application) are being executed at the same time, thus rendering them unable to process emails. The cause and solution is described in the above post.
